New records of Bactrocera invadens, B. zonata and other fruit fly species in Bhutan

A survey on Bactrocera and Dacus species (Diptera: Tephritidae) was conducted in Bhutan from 2000 to 2005. 24 Bactrocera and 5 Dacus species (including pest and non-pest species) were identified in Bhutan. Two new species, Dacus dorjii and D. fletcherii, were described but these are not plant pests. During this survey, several fruit flies were reported for the first time in Bhutan, in particular Bactrocera invadens and B. zonata.

Pest species which are reported for the first time in Bhutan:
Bactrocera correcta
Bactrocera invadens (EPPO Alert List)
Bactrocera tau
Bactrocera zonata (EPPO A1 List)

Other pest species found:
Bactrocera cucurbitae (EPPO A1 List)
Bactrocera dorsalis (EPPO A1 List)
Bactrocera minax (EPPO A1 List): Drew et al. (2007) do not mention this as a new record, but the EPPO Secretariat had no previous records of its occurrence in Bhutan.
Dacus longicornis (considered as a minor pest).
